How can we give authorization based on business rules, e.g. Limited time access to a feature (subscription)?

You can define a condition in a VG action to compare a subscription date with the current date.
You can also update a property with an expression like:
cb_save.visible = (limitDate > System.Datetime.Today).

In this case, cb_save remains visible as long as the current date does not exceed limitDate.
